Schneider Electric BSH1002P11A2A Lexium 05 BSH 3.4 N·m 2500 rpm 100 mm Flange Keyed Shaft Servo Motor

The BSH1002P11A2A is a Schneider Electric Lexium 05 BSH low-inertia AC servo motor rated for 3.4 N·m continuous stall torque at 2500 rpm nominal speed, built on a 100 mm international standard flange. It uses a keyed shaft and ships without brake, paired with Lexium servo drives via a single-turn SinCos Hiperface absolute encoder.

Selection Notes

At 3.4 N·m continuous stall torque on a 100 mm flange, this is the low-inertia class of the Lexium 05 line, suited to fast point-to-point and cyclic motion (pick-and-place, indexing) rather than constant-load conveying. The keyed shaft gives a positive, slip-free torque connection for direct coupling, the standard interface across the BSH10xx frame. It ships without brake, for horizontal or balanced axes where the LXM05/LXM15 drive's regenerative braking holds the load during a stop; where the axis must hold position with the drive off, the equivalent 'F' brake variant of this same frame is the one to specify. The single-turn SinCos Hiperface absolute encoder (131,072 counts/revolution) reports exact shaft angle within one mechanical turn without a battery, so the drive reads position on power-up without a separate homing move for single-turn travel. Continuous stall current is 4.8 A and maximum permanent current 17.1 A: size the paired LXM05/LXM15 drive to this continuous rating rather than the frame's peak figure, and re-check drive sizing before substituting a different torque variant of this same 100 mm flange into an existing design.
